SQUEEZER.

Specification of Letters Patent.

Patented' Apr. 28, 1914.

To all whom it may concern.' Y

F. BRAD- LEY, citizen of the United States, residing at Chicago, in thecounty of Cook and State of Illinois, have invented a certain new and useful Improvement in Squeezers, of which the following is a. full, clear, concise, andf exact description, reference being had to the this specification.

My invention relates to machines or implements for squeezing containers to eHect the discharge of their contents and is of particularlservice for collapsing collapsible tubes such, for example, as are employed,

for packaging tinting colors or oil colors,

means for subjecting the discharge end of.

collapsible tubesto collapsing pressure exertedlongitudinally of the tubes and the balance of. the tubes to collapsing pressure exerted'transversely of the tubes. By means of these two collapsing operations the entire tube contents'are sure to be discharged since the comparatively thick and somewhat rigid conical shoulder walls at the discharge ends of the tubes are merely flattened from their dish form and are not buckled and bent so as to form material trapping spaces within the tubes. Furthermore, pressure exerted laterally of the -tubes upon the conical shoulder walls at the discharge ends thereof would likely be followed by rupture of the tubes l'where the shoulder walls thereof join the complemental wall portions.

The machine ofmy invention is preferably stationarily supported and is desirably so positioned that the tubes or other containers to be collapsed will be held upright therein,

showing the preferred embodimentthereof and in which drawing- Figure 1 is a side elevation, partially in section, of a machine constructed in accordance with the invention, an alteredposition of some of the parts being indicated by dot and dash lines; Fig. 2 is a front 'elevation ofthe structure as it appears in-full lines in Fig. 1; Fig. 3 is a sectional View 011 line 33 of Fig. 2 with parts, however, in altered positie-ns; Fig. 4 is a sectional rear elevation of a part of the structure on line 44 of Fig. 1; Fig.'5 is a sectional plan view on line 5 5 of Fig. 1; and Fig. 6 is a longitudinal sectional view showing` a tubein a partially collapsed condition, the lower end of the tube requiring further collapsing-operation. 1

Like parts are indicated by similar charactersof reference throughout the different figures.

The machine is preferably stationarily disposed, to which end it may be mounted upon a bracket 1 secured to a vertical support 2. An inverted uncapped collapsible tube 3, or other object to be operated upon, 1s support-ed -upon a bracket 4 which in turn is anchored at its rear end to a vertical finger support 5 slidably ysupported in the bracket 1, to which finger support 5 the bracket 4 is adjustably secured by means o-f al set screw 6. The bracket 1', in addition to constituting asupport for the machine, also carries a portion 7 at its front which constitutes a squeezin'gjaw. As this squeezing jaw is thus preferably 'made stationary,

the collapsible tube is supported upon thel 3. The squeezing jaw 9, which is complemental to the jaw 7, has'a ixed pivot upon the bracket 1 at 10. This jaw 9 ,carries a cam element 11 which is adapted to be operated uponl by a cam roller 12 journaled -near the handle end of a hand lever 13 which is provided with a stationary pivotal mounting at 14 upon the bracket 1. A finger 15 projects' from the cam element 11, the hand lever 13 in'its idle position (indicated in Fig. 1) positioning the roller 12 to the rear of the vertical line passing through the pivot axis at 14 whereby the cam 11 and the jaw 9 `fixed with respect "thereto are held, when idle, in the position indicated by full lines in Fig. 1. When the tube is to be collapsed the slide block 8 is moved outwardly so thatthe uncollapsed tube maybe vertically postioned against the jaw 7 as indicated in Fig. 1. When the tube is thus positioned the hand lever. 13 is drawn forward until it occupies the ultimate position indicated in Fig. 3, during which movement of said hand lever the portion of the tube in engagement with the jaw 7 is collapsed, a result which is due to the fact that the center of the cam 11, when occupying the position indicated in Fig. 3, is sutiiciently below the pivot 14.

Collapsible tubes are usually provided with folds 31 to accommodate which the jaw 9 is provided with a recess 91. I/Vhen the hand lever 13 has thus collapsed the part of the tube 3 which has been pressed by the l j aw 9 against the jaw 7, the part of the tube below the jaw 7 1s now only partially collapsed as indicated in Fig. 6 and -is adapted to be completely collapsed owing to the parallel relation between the sliding holder 8 and the horizontal jaw element 16 (carried by the bracket l) and the aw element 17 (in fixed relation to the cam 11 and jaw 9) which ha's been brought to a horizontal position when the lever 13 has been depressed to the position indicated in Fig. 3. The lower surfaces of the jaw elements 16 and 17 are included in the same horizontal plane when the parts occupy the position illustrated in Fig. 3, the neck 18 of the partially collapsed tube then having its axis substantially in alinement with the middle of the space between the jaws 9 and 7, owing to the movement of t-he holder 8 in the general direction in which the jaw 9 exerts collapsing pressure upon the tube. A hand lever 19 has fixed pivotal connection at 20 with the bracket 1 and is connected at its rear end by a link 21 with the slidably supported vertical finger 5, as indicated clearly in Fig. 3. When the hand lever 13 has effected` adjustment of parts indicated in Fig. 3, the hand lever 19 is depressed whereupon the finger 5 is forcibly elevated to move the holder 8 forcibly upward against the composite jaw or squeezing member 16, 17 to collapse the portion of the tube which is shown in Fig. 6 to be but partially collapsed, the set of jaws or squeezing members 7, 9, and the set of jaws or squeezing members 8, 16, 17 thus exerting collapsing pressures that are relatively transverse, upon different portions of the tube. The holder S thus constitutes a squeezing jaw o r member which is complemental to the composite jaw 16, 17, A bracket 22 may be located below the ltube 3 for the purpose of supporting a removable receptacle 23 beneath the tube that is being collapsed to receive the contents discharged from such tube.

By means of my invention the thicker conical end shoulder wall 24 of the collapsed tube is relieved of pressure exerted laterally of the tube and is subjected only to pressure exerted longitudinally of the tube to be merely flattened, the machine thus insuring the discharge of all of the contents of the collapsed tube, the complete collapsing of the tube being unobstructed owing to the manner in which the pressure is applied to the wall 24, the result of the collapsing operation being clearly indicated in Fig. 3.

While I have herein shown and particularly described the preferred embodiment of my invention I- do not wish to be limited to the precise details of construction shown as changes may readily be made without dey parting from the spirit of the invention.

Having thus described my invention I claim as new and desire to secure by Letters Patent the following A squeezer including a pair of squeezing members, one of which is movabletoward the other; and a holder for the object to be squeezed in movable relation to both members, said holder being mounted freely to be moved by said movable member in the general direction in which squeezing pressure is being applied by such movable member, said holder being also movable toward said lnembers transversely of the general direction in which pressure is applied to the object by said movable member whereby a portion of the object projecting beyond said members may be squeezed.

In witness whereof, I hereunto subscribe my name this 18th day of September A. D.,

FRANKLIN F. BRADLEY. Witnesses:
